From the Preface: For many years there has been felt the want of a small and reliable Masonic Pocket Companion, which would be of value to the young Mason, by giving him full information in all matters connected with the ritual and customs of the Order, and also be an aid to the memory of the older brethren. With this view the Pocket Lexicon has been compiled and carefully revised. Nothing is contained in it that is not strictly correct, and confined solely to the three degrees of Antient Freemasonry. It has already been approved of by three of the Grand Masters and many Past Masters.
